I don't recall NH enacting a law banning e-cig sales to minors (as occurred in CA, UT and MN).
Regardless, this is very good news for e-cigarette consumers and vendors, and is bad news for the national offices of CTFK, ACS, AHA, ALA and others that want to ban e-cigarette sales to adults.
Don't know when the NH law was enacted (the article said it was introduced in 2009), but it may have occurred before those organizations changed their policy in April, 2010 to oppose legislation banning e-cigarette sales to minors. But since Breathe New Hampshire (which I'm almost certain is affiliated with ACS, AHA, ALA in NH) just gave the legislator an award, it appears that they've boldly decided to reject their national office's policy of banning all sales of e-cigarettes, which is good.
Hopefully, more state offices of ACS, AHA, ALA will buck their national policy and support legislation to ban e-cigarette sales to minors, which significantly reduces the likelihood that the same legislature will enact a law banning all e-cigarette sales.
